add function to generate the arguments to a module

[smwindecker]

added a function called ModuleArguments, which takes the module name and returns to the console the function's arguments. It only returns those a user can define (so not including the zoon-specific . files).

@smwindecker You evaluate the module in the global environment to then be able to get the formals. To avoid this function appearing in the users environment could you evaluate it in the local environment of the function or alternatively remove the function from the environment after you have got the formals? @goldingn can probably advise

[smwindecker]

Thanks @AugustT I'll revise.

[smwindecker]

did that do the trick?

[AugustT]

Looks good to me... In it goes :)

Haha, closed before mergeing, whoops. Should be in the master version now
